About Us

BLOCK21 was created by people who have come from a technology recruitment background within software development, data & design. We have a passion and vision of helping drive change within the Blockchain, Crypto & web3 space. We know that adding our experience together with our passion will enable us to be a great partner for some of the most interesting and exciting companies within the Blockchain space. Our consultants have many years of experience within the technology space, working across the globe, so have built-up great networks to allow us to help you find top talent quicker and more efficiently. 

That is why here at BLOCK21, we don't  consider ourselves as just another agency, we partner with companies and then act as part of the organisation, because we know that the whole process of hiring can be tough and time consuming, especially when you are trying to grow at a fast rate. We are here to take that responsibility away from you so you can give more attention to other important aspects of your business. We will focus on the full lifecycle of the process starting from the first contact all the way until the candidate has signed the employment contract.
